Drug International Ltd is one of the largest company who has inhaler facility to produce eco-friendly HFA based inhaler products. The Company is currently the largest producer of MDIs in Bangladesh. Drug International offers wide range of products for treating asthma, COPD, allergy, and other respiratory disorders. Earlier MDIs were produced with CFC, that means chlorofluorocarbon, propellant system. But increasing environmental concerns have called for CFC phase-out as CFC depletes the ozone layer that shields the planet from ultraviolet radiation.
